ROM To SpareRunning out of memory? Power up with an add-on CD-ROM drive.

A single CD can store moreinformation than 300 3.5-inch floppies and is much cheaper toproduce.

如果你的电脑或laptop pre-dates the advent of CD-ROM, don'tworry: There's no need to scrap the whole system. You can buyan external CD-ROM drive that can be cabled to your PC'sparallel (printer) port.
